.Be it known that I, PAUL- M. RAINEY, a citizen of the United States, residing .at lli/Test Hoboken, in the county of Hudson and State of New Jersey, have invented. certain new and useful Improvements in Telegraph Systems, of which the following is a full, clear,q concise, and exact'description.

This invention relates to telegraph systems. An object of Ythis invention is to provide a system whereby a plurality of telegraph messages origjriiiatingir at .separate stations may be transmitted over a plurality of branch lines or extension circuits to a main station, `where they al'e automatically and simultanic'iuslyl transferred to a main line circuit -for transmission thercover, and vice versa. s n Another object is to provide a' system which is eiicieiit and reliable. i

'In carryingv out this invcntionthere is provided distributor means. and electroresponsive switching means, coordinated with a Vplurality of line circuits in such a manner that predetermined storing or holding and repeatingr of telegraphic message impulses on a tivo-way service basis may be automatically performed withrespectto the line 'circuits.

This invention is illiistratedin the. accom'- panyingT drawing, in which Fig. 1 is a comhincd perspective and diagrammatic illustration ol a telegraphic equipment suitable. for I a main station: while Fig. 2 `similarly illusbranch or sul'istation. In' order to siiiiplif)` tho drawing ity has been prepared to include -only so much of a telegraphicequipment as will be necessary to a clear understanding' of' the present invention.`

The service `.features ofthe present system .provide that. incoming message impulses from a duplexcd main line conductor 5 (Figi: 1) may automatically affect.. a group of selecting magnets l (Fig. 2) to establish action of inst-rumentalities (not shown), whereby such impulses result in a printed message. .Furthermore thc eiicct ot predetei-mined coinl'iinations of impulses prepared .at a lgroup of transmitting contacts L may at the sanicftinicvbe 'delivered to the main line conductor 5 and in turn establish :if printed record vat a distant .station (not shown). v

`For convenience 'the embodiment chosen for illustrating the features of the present invention has been planned on the basis of a' so-called ive-unitcode, that is, the selection of each character or other operation necessary to the permutations of five successive units of current. Accordingly, at a distributorsection' printing` of a message is effected through various polarity combinations or efe tacts 9:3 to 9!) ofl a rack type distributor F I -ivorked by the repeated impulses, whence the impulses reach a line thereover complete polarizedl line relays 120 and 125 station (Fig. 2). In Working the line relays 120 and iQ, these impulses cause a second conductor 8 and circuit through two" attlie subrack distributor G to be operated and through successive closings of its tive com tarts 95 to 99 predetermined selections are made at a group of selecting magnets-K.. Such selectingof the magnets K is on the basis that positive impulses from the line conductor 5 ivill cause corresponding ones ot the magnets K to be operated, while nega tive impulses from the line 5 xvill not result in operation oic these magnets. This distinction in selectingis arranged througii the provision oi a set of contacts 126 on the trates telegraphic equipment suitable tor anegative responding line relay 125. whereby the control from this relay is limited to operating a stepping' magnet 101 of the distributor (t. operating the distributor G the relay 19.0 is also provided with 'contacts 121 whereby a source of current. 123 may be included throughdistributor contacts 95 to 99 to operate the magnets of ,group K. linpulses that result in fthe operation of selecting devices are usually termed marking impulses. while impulses that '.l`heret`ore, as arranged in the presentsystem` positive ini'- pulses correspond with marking impulses .vhile negative impulses serve as spacing iinpulses.v A

ln transmitting messages from the substation (Fig'. 2) various su'itchiiigoinliiiia UOHS may be Prepared en are contacts L" In addition to contacts 122 forv aff d'o not. so -result are. f termed spacing impulses.

and through the operation of the distributor G, the five contacts to 94 thereof successively establish these contacts L with a line conductor 9 provided to extend the circuit to Five corresponding contacts 90 to 94 of the distributor ll,

section B, thence ductor 5. Y

The three rotary distributors A, B and C may comprise separate units as shownv or they may be formed into a single distributor unit in which the three arms 12, 42 and 72 would be driven in unison in a counterclocliwise direction and also in synchronism with a corresponding distributor' connected to the line conductor Although no driving or synchronizing arrangement for the distributor is shown such equipments are Well known in the art.

rl`he rack-like distributors F and G shown in perspective. are substantially alike and tor convenience the same reference characters have been used in designating corresponding parts in each. therefore. a brief description more particularly directed to the distributor indica-ted as (irr will suiiice to convey clear understanding ot the operating features ot both distriliutors. Accordingly7 contacts 122 and 120 ot the line relays 120 and 1257 respectively, control the open ation ot a stepping magnet 101, the armature of which acts to more longitudinally a to the main line concontact actuating beam 1025fwhich carriesv live transverse arms 104. "lhe beam 103 is positioned aslant the Contact members 90 to in such a manner thatas a stepping pawl drops to a next lower step in a rack 107 at each torwa-rd movement ot thc beam in response to energization of the magnet 101, successive ones ot' the transverse arm' members 104 will come into alignment with correspondingr pairs of the contactmembers as contacts 00 and 95, 91 and 96, etc. On releasing of the magnet 101 a retractile spring 102 thrusts the beam to cause one ot' the arms 104 to press together its associated pair or' the contacts -90 to 99. Retna-tion of the beam 103 also affects the stepping pawl 105 to move the rack 107 longitudinally in its supporting'base, the holding pawl 106 thereupon drops to a next lower step of the rack and holds it against the tension of a retractile spring 108. y/Since the impulses that may reach the line relays and 125 are uniformly continuous$- as will present-ly appear, the beam 103 isystepped downwardly in' a rapid manner and successive pairs ot' the distributor contacts closed until on arriving at the lonf'est. step the topinost one of the arms 104, onclosing thc contact members 94 and 99D also closes the contacts 100. The latter contacts complete a circuitfrom. a source of current-at themagnet 101, the Winding of this magnet, conductor 128, con

tive storing or repeating. refays comprising a group E, a distributor4 tact-s 100, conductor 133, contacts 141 ot :i relay 1405 thence jointly through the winding of this relay and the Winding of a. relay 135, continuing thereafter through the winding of a relay 147 to an earth connection. Operation of the relay establishes through its contacts 136 a holding circuit for the stepping magnet 1017 and through its contacts 137 establishes an operating and holding circuit for a restoring magnet 110. ln operating, the outstanding end of the armature 111 of' the magnet 110 lifts the holding pawl 106 and the beam 103 resting thereon to their uppermost position in which they are shown in the drawing, following which therack 107 is retracted by the spring 108. Operation of the relay 140 establishes a lockingcircuit `from a current source 144 by way of contacts 143 and its contacts 142 whereby holding of this rela-y 140 and the relays fected.A Contacts 148 of the -relay 147 include a source of current 146 to operate a magnet 150'for service which will presently be described. By means of circuits and de vices not shown the relay 140 on operating initiates a so-called printing cycle to record a character which may have been predeter! minedlyslected through the group of magnets K. Mechanism not shown, but active on the completion of. a printing cycle,` momentarily separates the contacts 143, thereby releasing the relays 140, 135 and 1475, 'and in t-urn the stepping magnet 101 and the restoring magnet 110 of the distributor. lReleasing of the stepping magnet 101 permits the beam 103 to be retracted and inthis normal or starting position the lowermo'st. transverse arm 104 establishes the closing -ot' distributor contacts 90 and 95.`

The transmitting contacts L arel shown in a simplified manner for convenience ot circuit illustration; therefore, in this system the equivalent of these contacts may preferably consist of contact devices adapted to be controlled by means of a punchedv or perforated tape, as Well understood in thc art, the tape and contact mechanism to be under such control of the magnet 150 that as each code unit or set-up of five impulses is transmitted, such set-u i will be cleared out and tlie tape advanced to eect predetermined selection of thecon- `tants J for a next five-unit cycle of impulses.`

T he duplex equipment ofthe main line conductor 5 has form in order tb further simplify the drawing, a polarized relay 6 being.,r interposed between the line 5 and an artificial lineindic-ated by the characters A L. The connective point for incoming message impulses is at the armature or movingecontact member of this relay While the co'rpect-ive point for outgoing message impulses 1s at the neutral point between the two coils of this reo'f the contacts been shown in elirmental` 135'and 147 is ef- MM50-ie lay; therefore, uut-going impulses are neu- 'tralized and non-eti'e'ctive in the line relay 6, all of which arrangement and operations are well understood in the art. As indicated by the conventional plus and minus signs, incoming impulses of positive current more ,the armature of the line relay 6 to close its contacts 7, while incoming negative impulses more -the armature to separate its contacts, in Which-position the armature is incllectiv-e,

`ln order to bring out detailsof operation not touched upon in the foregoing general description of this invention it will be expedient to now trace a single'positive impulse of incoming current from the main liuc such impulse ma be assumed to be the lirst impulse of a ve-unit code combination. The action of an outgoing inrpulse of positive current which may also be assumed as a tirst'impulse ot a five-unit code combination, the movement oli' lwhich is in art coincident with action of the incoming impulse, will also be traced and described.

The incoming impulse of positive current l.from the line 5 traverses the two serially.

connected windings of the line relay 6, thence over the artificial line L to an earth connection. The armature of thc 'relay is thereby moved to establish its contacts 7, and assurnug that the trailer arm 12. ol the diS- tributor section A in its regular travel is at the same moment lover a contact segment, 13 a circuit will bey thereby completed from the earth connection, the contacts 7 ofthe line relay 6, conductor 10, lcollector ring 1l, trailer arm 12, segment 13, conductor 14. the winding,r of a relay 15, conductor 2l. tlul contacts 23 of a relay 22 to a grounded current source In responding the relay l5 closes its contacts 17 to establish a selfloclring circuit further completed through a grounded bus conductor '16. Through the contacts 18 oi the relay 15 another circuit prepared which will be presently referred to. Leaving the incoming* impulse for the fussent, attention will be directed to the outgoing impulso. -Accordingly, let. rit be assumed that a prepared combination for a tire-unitrode oifirnpulsels has already been establisiiell by apunched tape on vthe contacts il, nfi'iich preparation'- has, among other operations, closed the transmitter contacts 131, thereby includingl a groundedv bus conductor 1550 by way ot' the closed contacts 90 of the distributor (l 'with a line conductor 9 which at presentstands openat the con-A tacts 87 of a. relay 86. y

-ritt'this stage of th'e operations and with! .out extending the description to considerv l Athe remaining,r four incoming and four outgoing impulses of the assumed combinations, attention will ne immediately referred to suchinstant' as the trailer arm 72 ofthe distributor section C willhave arrived over the segment 73. This position ot' the trailer arm establish a circ-uit from. a current source 7() to a collector ring 7l, the trailer arm 72. the segment 7 25, a vconductor 74. and the windingr of'a starting relay 75 to an earth connection. '()perationrof the relay establishes a self-locking circuit which extends over its contacts 76. a conductor 78, the contacts 2l of the clearingmut relay to a grounded current source 26. Operation of the relay 75 also completes a. second circuit extending from the relay 15 previously described as operated and held in a locked position. This circuit may be traced from a positively poled current source 29, a bus c mductor 3l). contacts 18 of the relay 15,

a conductor 20. contacts 95 of the distributor i the line conductor 9,already traced from the earth connection at L, which path continues over a bus conductor 69, contacts' 9u of the distributor 1".,oonductor 50,' the windingr of a relay 45, a bus conductor 51, contacts 53 of a restoring relay 52 to a source 'of grounded current` 5:'1. Operation of the relay l5 thereby effected establishes ay self-locking circuitthrough its contacts 47 by way of a grounded bus conductor 46. The contactsll of the relay llrprepare an impulse circuit which will be considered presently. A

Referring to the line relays 120 and 125, the positive impulse. of current already traced as present therein, operates the4 relay 120, while the. relay-Q25 remains inert. The polarizing effect forthese relays being established by current act-ion from the source 123 through the right-hand winding` of each relay. .operation ofthe relay 12() establishes a circuit from the current source 123, contacts 121 of this relav, 'a bus conductor 124,

contacts v of' the distributor G, and the winding of a selectin-g magnetlQQ to earth.

vA second vcircuit may. also betraced from the source of 'current atthe stepping mag-- net 101, the winding of this magnet, conduc- 'tor 127, contacts 122 *of` the relay 120 to earth.- Thereupon the magnet 101 Withdraws the' beam 103 to permit the contacts 90 and 95 to separate and also allow the stepping pawl 105. to lower the beam by droppir7uf into the next lower step oi the rack 10 Referring now tacts 88 of the relay 86, operated as described, include a source of current 89 Wit-h al bus conductor 83, thereby establishing currenb Vto the distributor F, coni 'l action through the stepping* magnet 101 ot this distributor, whereupon the beam 103 is withdrawn to separate the'contacts 90 and 95, and permit the stepfiingpawl 105 to drop into the next lower-step of the rack 107.

IIt will be noted that in the group D the relays and their circ-uit connections are typi cal as compared one with another; therefore 1t 1s obvious that the efl'ect of the last Iour impulses of the hve-unit code assumed to have been received from the line 5 into these i contacts 91, 99 and 100 closed. Therefore,

coincident with the iitth impulse and the operation of the stepping relay 86 and the closing of its contacts S8 to include the current source 89 with the bus conductou 83thc contacts 100 connect this bus conductor to a vconductor S4 energize the left-hand n'in l ing of a clearingeout relay S0. 0n operating, the relay establishes a self-lockingr circuit through its right-hand winding, its contacts 92, a conductor 78, contacts 2t of the relay 22 to the current source 2G. The contacts 81 of the relay 80 establish a current sourcey with the vbus conductor 83. thereby energizing this bus independently of the stepping relay 86, which may release immediate y on cessation of the signaling impulse from the last relay in group D. In addition to providing` the locking cir-cuit described, the contacts 82 of the relay 80 also establishtbe current source 2G to o-perate the distributor clearing-out magnet 110 of the distributor F. The stepping,T magnet 101 of this distributor,,having` already operated under current from the bus S3, has Withdrawn the beam 103 to effect clearance oi the tive transverse arms 104 thercoiu with respect to tbc contact members to 99. Therefore, action ot the magnet 110 lifts the holding pawl 100 and beam 103 to their {irst or normal position as already described.

Operation of the magnet 110 also connects a source ot' current 112 over contacts 113, ,a conductor 11a and the winding ot the lockrelease relay 22 to earth. The relay 22 thereupon operates and by separation of its contacts 23 disconnects the-current. source 25 from the bus conductor 21 common to the Winding' of each relay in the group "D, thereby disconnectingball ot' the relays ot this group. Separation of the contacts 24 of the release relay 22 disconnects the current source 24 from the several paths,ynamely, the winding' of the relay 75, the \righthand winding of the relay 80, and the Wmding ot the distributor restoring magnet 110'. Releasing of the magnet 110 separates its contacts 113 to disconnect the relay 22, Where-4 upon the equipment is aga-in in its normal condition except for the outgoing impulse which will presently" be further described.

It will be understood thatthe various operations of the distributors F and G are re lat-ively in step or time phase one with the other; therefore, the releasing or restoring operations just described in connection with the distributor F of course took' place coincident with the restoring operations already described in connection with the distributor G.

Referring to the relay 4,5 of group E, retained locked by the action of the outgoing impulse already traced to thatA point` letit be assumed that the trailer arm 42 of the distributor section B has arrived over a segment 43 of that section.l This position of the arm 42 establishes a circuit from a current source 57 of positive polarity, a bus conductor 58, the contacts 48 of the relay 45, a condutor 44the segment 43, the

trailer arm 42. a collector ring 41. aconductor 40 to the outgg'oing connective point' on the duplex equipment of the line conduc- 'tor 5, thereby disposing of the outgoing impulse'.

The relays and circuit connections thereof comprising the group E arc, as may be noted, typical as compared one with another, therefore, the. last four impulses forming the assumed five-unit codewould have been dulystored successively therein following,r the storing of the first impulse at `the relay 45. successively passes over the associatedsegments in the quadrant 2 of the distributor section B, impulses of current corresponding' in polarity with the previous selective conditioning of these relays would be released to the line conductor Following the release of the fifth or the last one ot an impulse combination from the relays 1C to the line conductor 5, the trailer arms ot' the. distributor sections will. have advanced to the respective quadrant zones 3, whereupon a circuit will be established at,4 the section C which may be traced from a current source 70, the collector ring 71, the

Accordingly, as *the trailer alrm.` 42- trailer arm 72, a segment 56, a conductor are established with negatively poled cuis rent sources; For the relays l') this current supply is from a source 2T ot negatire polarity, and a bus conductor 28 While a i'iegatively poled current source :39 and a bus conductor G() suppl)v theiimmal contacts of the relays inv `the group l Although negative impulses areI transmitted and received over the main line conductor .7 it 1will be apparent that for aI transmitted impulse oi negative current a corresponding one of the transmitter contacts L may remain open.l since a corresponding relay in the group E may for such impulse remain inert. The same results obtain for incoming negative impulses, as under such impulses. the contacts of the line relay 6 are disabled; therefore no circuit is completed through a corresponding one of the relaysD and accordingly such relay remains inert.

Further service features of the present system provide that messages may be transmitted from the substation over the mainline circuit 5 independently ot' or in 'the absenceot incoming messages from this vmain line, and rice versa. Such independent transmitting `or receiving of messages is eilected through the continuous operation of the distributor sections A, B and C. From the description of the system already given and an inspection of the drawing `it will be obvious that, irrespectiveof incoming or outgoing impulses by way of the main line 5, continuing operation of the distributors A, B and C will'in turn render code cycles each comprising lire negative impulses to be established from the relays of the group D. These successive vnegative impulses by operating the stepping control relay 66 cause the distributor-F to be correspondingly Worked, and the same negative impulses by operating the line relay 125 at the substation cause the distributor G at lthat point to be Worked without causing 'operation of the selecting magnets K. y

ln the matter of service capacity of this systeir;Av it may be readily extended by -in-V cludiri'g other telegraphic equipments with' the idle segments-in the zones or quadrants l, 3 and .fl ot the distributor sections A, B andC.4 lit desired three additional equipments, each identical with the equipment shoun, may be respectively included with the three idle quadrants of the distributors, thereby increasing the capacity of the system fourfold. Such branchings oi forkings of the quadrants lL 2, 3 and fl-.may serve that number of differentsubstations.

means 'for transmitting message impulses individually connected to the contacts of 3o corresponding ones of said relays so tlsit said relays control the character ol the inipulses transmit-ted by said transmitting contacts.

19. In a telegraph system, a sunflower a5 device, means to operate said sunower device uniformly, a series of relays, an electrical connection between the coils of said relays and said sunflower device, a transmitting device started into operation at the beginning of each signal and automatically stopped at the end of each Signal, said transmitting device including a series of transmitting contacts, said contacts being indvidually connected to the contacts of corresponding ones of said relays so that said relays control the character of: the impulse transmitted by said transmitting contacts, a control relay, means to operate said control relay when any of the relays of said series are operated, and means controlled by said control relay to start said transmitting device into operation at the beginning of a signal.

In witness whereof, I hereunto subscribe my name this 14th day of July, A. D., 1917.
